1- Why is it that hunters develop an emotional bond with their in-game-pets?(im not here to make the argument that they are just bits of code, I dont think you guys are stupid). Im just wondering if it stems from a RL experience with a lost pet, and wow has helped you coupe with the emotion.
Reality? Some of us spend more time with our ingame pets then our family

2- Why is my quest to get an achievement assumed to be less important than you taming the pet. In my eyes they are the same.(Only because current content does not require a specific(rare pet) to max your DPS. If it did than obviously it would make more sense.
Because you kill and then go on to the next one, I tame said pet and he can stay around for the rest of my wow gaming experience. It may have been a mark off your achievement, but to me that King Krush was my raiding buddy who was well known to my guildies.
The thing is I spend days/weeks/months to make a possible new raiding/questing/pvping buddy but I love the skin and you spend that time for a little check mark which with other chermarks gives you one achievement point. My achievement point is when King Krush goes and tanks Litch King, or when Loque saves me with his heals in pvp.. so thats my take on the difference
